Can you describe a dobutamine stress test?

Can you describe a dobutamine stress test?

Drug induced stress: If exercise on a treadmill is not an option (too much stress on the heart) due to a person’s medical condition, may use an intravenous medication called dobutamine. Dobutamine causes heart to beat faster and will mimic the effects of exercise on the heart. Stress tests usually can be nuclear with radiotracer or with echocardiography. ...Read more

Stress (Definition)

Stress affects most people in some way. Acute (sudden, short-term) stress leads to rapid changes throughout the body. Almost all body systems (the heart and blood vessels, immune system, lungs, digestive system, sensory organs, and brain) gear up to meet perceived danger. These stress responses could prove beneficial in a critical, life-or-death situation. Over time, however, repeated stressful situations put a strain on the body that may contribute to physical and psychological problems. Chronic (long-term) stress can have real health consequences and should be addressed like any other health concern. Fortunately, research is showing that lifestyle changes and stress-reduction techniques can help people learn ...Read more

Could be increased heart rate, could be nausea or any other physical symptom of anxiety. So, if palpitation and rapid heart beat is usually a trigger for your panic, then see your psychiatrist so he can prepare you for the test to alleviate the risk of triggering an attack. ...Read more

What's the difference between a lexiscan stress test & a stress echo dobutamine test? I have had the lexiscan before.

What's the difference between a lexiscan stress test & a stress echo dobutamine test? I have had the lexiscan before.

Nuclear/ Echo stress: Lexiscan stress generally performed with nuclear isotope, which shows blood circulation(perfusion), comparing with medication lexiscan(stressing heart) and at rest. Dobutamine echo we are looking at wallmotion of heart with medication dobutamine( stressing heart )and at rest to see they show any differences to detect blockages ...Read more

Is it okay to drink caffeinated drink before a dobutamine nuclear stress test?

Yes within reason. : The caffeine does not affect the nuclear tracer or the dobutamine. However, most protocols want you to have not eaten or drank for 8 hours. Additionally, in my lab we withhold caffeine from all stress test patients because some of them will need to be converted to other types of stress that can be affected by caffeine. This way all options are available while the patient is present. ...Read more

Have copd, asthma, am clastrophobic have cramps in my legs after venous closure surgery. worried about dobutamine stress test & thinking of cancelling?

Stress Test: For this test you will not have to run or walk on the treadmill. They will give you medicine to elevate your heart rate. The machine they will use to take pictures of your heart is wide open and will not enclose you. I have had this test myself several times . If you are really nervous your doctor can give you a medicine to relax you before the test. You will do great. ...Read more

Could you please describe functional capacity on a cardiovascular stress test?

Functional capacity: It's how long you're able to exercise and the load applied (for example, on a treadmill: 10 minutes reaching a peak speed of 4.2 mph at a grade of 16%.)these parameters result in a number called mets (metabolic equivalents). There are standard tables that predict normal functional capacity in mets based on age and gender. ...Read more

Will a nuclear stress test make me radioactive? I’m having a nuclear stress test, and i need to know if it’s safe for me to babysit my grandkids after it? Will i be radioactive? Could i be dangerous to the kids?

Will a nuclear stress test make me radioactive? I’m having a nuclear stress test, and i need to know if it’s safe for me to babysit my grandkids after it? Will i be radioactive? Could i be dangerous to the kids?

You : You will be sufficiently radioactive to set off alarms at airports, ferry terminals, and border crossings. The sensitivity of these devices is high on purpose. However, the amount of radiation a patient emits after a cardiac nuclear scan is not considered dangerous to others. Notice that the technologists who perform these tests do not wear lead or other radiation protection and they are around "radioactive" patients every day. For the sake of completeness, however, i will add that pregnant women should not undergo this test and anyone who thinks they might be pregnant should have a pregnancy test before having any kind of radionuclide scan. ...Read more
